Hello. First SparkFun project, help needed.
Obtained a DMX to LED Shield, and ESP32 Thing Plus, attached stacking headers and installed/updated the libraries. Now I wish to start with Example2-DMXInput.ino and mod it to trigger a relay. The controller is not responding to DMX data over XLR cable. The compile-time messages are these.

To the example code I added some serial prints and instructions to blink LED-13 in response to incoming data. The serial output shows this.

The controller detects only an unchanging zero value on all DMX channels involved.
My small voltmeter shows that 5V of USB power is present on the shield’s push terminals.
DMX data does correctly pass through the shield to other lights wired in the chain.
I suspect that the compile-time warning about undefined hardware SPI pins may be part of the issue. This message appears even when compiling the unmodified example code. How should I define these pins? Is that relevant to the problem? I haven’t seen this warning mentioned in other forum topics. Thanks for reading.
Hallelujah!
